Landiolol HCl

Medical University of Vienna · Phase 3 active Small molecule ✓ Verified May 2026

Landiolol HCl is a Beta-1 selective adrenergic antagonist (beta-blocker) Small molecule drug developed by Medical University of Vienna. It is currently in Phase 3 development for Intraoperative and postoperative tachycardia, Atrial fibrillation with rapid ventricular response in perioperative settings. Also known as: Rapibloc.

Landiolol HCl is an ultra-short-acting beta-1 selective adrenergic antagonist that rapidly reduces heart rate and cardiac workload.

Landiolol HCl is a medication used to prevent atrial fibrillation after cardiac surgery. It is administered as a low-dose intravenous infusion.

Likelihood of approval
56.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Cardiovascular Phase 3 risk -2.0pp
    Modern cardiovascular outcome trials are large + long; many fail to beat aggressive standard-of-care.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr
MHRA GB 2029–2031 +0.7 yr

Mechanism of action

Landiolol selectively blocks beta-1 adrenergic receptors on cardiac tissue, reducing sympathetic stimulation and decreasing heart rate, contractility, and blood pressure. Its ultra-short half-life (approximately 4 minutes) allows for rapid onset and offset of effect, making it suitable for acute perioperative and critical care settings where quick titration is needed.
